Where to Buy Faraday Isolators

Our polarization-maintaining Faraday isolator features low insertion loss, high isolation, high extinction ratio and high reliability and stability. The device is available with bare fiber or with a 900-μm jacket cable.

Edmund Optics free-space optical isolators incorporate a Faraday rotator and are specifically designed and manufactured to provide superior performance with high isolation, transmission, and power densities. Each option effectively reduces feedback in the external cavity of diode laser systems and blocks reflections from free-space fiber coupling. These isolators enable state of the art protection for the most stable lasers in the world and are ideal for demanding laser applications.

CSRayzer offers many kinds of optical isolators. The free space isolator is available with different clear aperture sizes, including diameters of 3, 5, 6, 7, 8 and 10 mm. The operation wavelength can be customized. Typical working wavelengths include 800/920/1030/1064/1550 nm, with wide adaptability. Using a high-power resistant TGG crystal and a Glan laser prism, the optical pulse damage threshold can reach 10 J/cm². The prism is designed with double escape windows.

Our free space isolator is composed of a birefringent crystal (or polarizer), a Faraday rotator and a half-wave plate. It is used in fiber lasers and can effectively stop back reflections.

TOPTICA’s optical isolators provide market-leading performance spanning the UV out to the NIR. Use the same isolators that make TOPTICA lasers the best in the world!

O/E Land's fiber-optic isolator works with any polarization state, and it features low polarization-dependent loss (PDL) and low polarization mode dispersion (PMD). The optical path is epoxy free, thereby enabling high-power applications. Being made with metallized solder package technology, this isolator is highly stable and reliable, meeting the Telcordia GR1221-CORE standard.
